QuantumScape (QS) reported second quarter 2026 results that showed a narrower net loss, which has prompted fresh attention on the stock. Investors are weighing what this shift in quarterly and year to date losses means.

QuantumScape’s latest earnings update comes after a sharp reset in market expectations, with the share price up 5.44% over the last day and 2.25% over the last week, yet down 30.82% over 30 days and 52.71% year to date. The 1 year total shareholder return is down 39.19% and the 5 year total shareholder return is down 76.13%.
